Solution

Locate the following file on the UMP server:?

(Nimsoft Home)\probes\service\wasp\webapps\jasperserver-pro\WEB-INF\applicationContext.xml?

Edit this file with a good text editor like Notepad++ (don't try to use regular Notepad, it will be painful... Wordpad might do it.)?

Find this section:?

?

<bean id="fileVirtualizerFactory" class="com.jaspersoft.jasperserver.api.engine.common.service.impl.FileVirtualizerFactory">?

<property name="maxSize" value="300"/>?

<property name="directory" value="${java.io.tmpdir}"/>?

</bean>?

Just below the <bean></bean> definition you should see something that says "comment the above bean and uncomment this one to use a shared virtualizer." ?Do that now.

To comment out the section, add < !-- right before the first bracket, like .?

Then remove the !-- and -- from the same place on the section you want to uncomment.?

When you're done, it should look like this:?

<!--<bean id="fileVirtualizerFactory" class="com.jaspersoft.jasperserver.api.engine.common.service.impl.FileVirtualizerFactory">?

<property name="maxSize" value="300"/>?

<property name="directory" value="${java.io.tmpdir}"/>?

</bean-->?

?

<bean id="fileVirtualizerFactory" class="com.jaspersoft.jasperserver.api.engine.common.service.impl.SharedVirtualizerStoreFactory">?

<property name="maxSize" value="5000"></property>?

<property name="storeFactory">?

<bean class="net.sf.jasperreports.engine.util.SwapFileVirtualizerStoreFactory">?

<property name="directory" value="${java.io.tmpdir}"/>?

<property name="blockSize" value="4096"/>?

<property name="minGrowCount" value="64"/>?

</bean>?

</property>?

</bean>?

Restart wasp after making this change and the issue should be resolved.
